Third place enough to go back to the top of golf's world rankings.
Luke Donald retakes the No 1 spot from Rory McIlroy
Donald has exchanged the top spot with the Northern Irish star and reigning US Open champion for the past two months.
The Englishman needed a top-seven finish this week to secure the top ranking once more. With a birdie on the par-5 18th to complete a final-round five-under par 67, Donald finished 72 holes on 17-under 271.
In a bogey-free final round, Donald birdied the par-3 third and ninth holes on the front side and added birdies on the par-5 11th and par-4 13th before his concluding birdie, which avoiding him sharing third with two rivals.
Two weeks ago at the US PGA Heritage Classic, Donald finished in a share of 37th place when he needed to finish eighth or better to keep idle McIlroy from passing him for the top ranking.
McIlroy had moved to World No 1 for the first time in his career last month.
At the front, Jason Dufner two-putted from 60 feet for a birdie on the second play-off hole to defeat Ernie Els and win his first PGA title in 163 attempts. It was heartache for South African icon Els, a three-time major champion whose win drought of more than two years continues.
